• Offset valves permit cleaning of gauge glass & its removal on line

• Wide choice of MOC

• IBR certified gauge for steam service on demand

• PTFE lined gauge for corrosive liquids

Salient Features

Construction & OperationGauge is fitted between two end blocks through gland packings. The gauge is mounted parallel to tank so as to form a close loop, causing tank liquid to seek its level in the gauge. ‘C’ channels/ tie rods are provided to protect gauge from accidental blows. End blocks are provided with vent plug, drain valve & integral offset valves.

TRANSPARENT TUBULAR LEVEL GAUGE “TTG”

Simple, low cost and reliable gauge for direct reading of clean liquid levels at low temperature and pressure conditions.

Special Features Glass Protector 3 mm thick perspex shield to protect gauge glass and for personnel safetyAuto Ball Check SS316 or PTFE ball to minimize liquid loss during glass breakageFrost-free 20 mm thk x 35 mm extension perspex shield to prevent frost formation on outer surface of gauge glass

for clear visual reading of liquid at low temp. Illuminator To provide uniform light along the length of gauge glass in poorly lit area. It consists of perspex reflector,

illuminated through a LED bulb, 80 to 250 VAC with Al. Enclosure IP65 /Ex d Gr IIB or IIC. The length of single illuminator is 1200 mm max.

Jacketing For preventing solidification of process liquid. It consists of a SS pipe with "NPT (F)” inlet & outlet at bottom & top end blocks for heating/cooling agent.
